Thanks for the note on Platinum, if you go to your local hobby store, =
you will find they sell glow plugs, for model airplane engines, with a =
small coil of .... You guessed it Platinum wire, as the element (and =
they survive for about 40 hours running red to white hot in the =
combustion chamber.. so the wire must be ok).. If I cant get enough, il =
phone a manufacturer, and see if they have any off cuts, ends of reels =
etc.

PS Plugs are only a couple of bucks each.

Mark,

I'd thought about doing something of the sort.  The reason I didn't=20
is that a MAF from the junkyard is going to be a lot less expensive
unless your attempt is pretty close on the first try (or unless your
time isn't worth much).

Didn't it take Edison 119 trys to make the first electric light?

On the other hand, you could learn a LOT about MAF during the=20
process.

And don't they use platinum ($$$) wire?
